THMA13: Phase calibration across frequency

Abstract
New communication systems are climbing the frequency ladder to access wider bandwidths for higher data rates in the next generation 6G and satellite links. Mixing concepts are often used to translate the IF signal to the target RF frequency. Especially if beamforming comes into play as typically used in satellite communication, a solid understanding of the phase conversion between IF and RF is essential as digital beamforming controls in the baseband and IF the phase for the RF and enables different beam directions. We will discuss a fast and easy calibration for VNA-measurements for fast and easy phase information.
